Anobject'of' theinve'ntlon is to provide a radio receiverof the abovetype, which is of relatively simple and compact construction that is easy to service; and whlc'h'ha's noneof the external char acteristic appearance of a radio but simulates" a'miit for an entirely different purposethat gives little or no indication of its utility as a radioreceiver: M I I Another object is to incorporatealiof-the' tune-- tio'nal' radio receiver elements-in a single suba'ssembly that readily admits of being mounted into a casing of odd shape to which the subassembly is conformed, and which" inuse' distributes the sound iii all directions with. superior sound effects.

As shown, the volume control member V and the extension shaft 3| thereof, occupy a considerably smaller diameter than the panel 20, the parts mounted thereon and the variable condenser C-thereiabove, Therefore, it is feasible and prefer'abletdredu'ce the upper part of the cylindrical casing to a frusto-conical section 36 about the volume control member V, and a generally cylindrical, preferably inwardly tapering, neck 31 about the operating shaft extensions 3| and 35. A pilot light 38 may conveniently be mounted on top of the condenser frame 24 and laterally of bracket 21.

It will be clear that the entire assembly as thus far described, may be introduced upwardly through the hollow base It! into the cylindrical casing l5. The assemblyis mounted in position, desirably bya cross strap 39 diametrically across the mouth of the loud speaker S and afiixed thereto as. by bolts 40, said strap having outturned ends that may be affixed as by screws 4! to the inner periphery of the bezel l4 and, if desired, further screws 42 ,may clamp the outturned extremities 43 of the strap to the lower rim ofv the bezel 14. Accordingly, the unitary structure. described is securely mounted casing.

The operating knobs preferably include a lowerknob which may have a skirt 4'5 telescoped overthe reduced upper rim 46 of the casing l5. That knob is affixed to the hollow operating shaft 35,by means of a set screw 41 depressed within a radial bore 48 in the knob. The inner shaft 3| has preferably an enlarged head or button 49 retainedin place, as shown above the knob 44,

' at the top of the unit. 1

- It will be seen that the receiver is readily tuned by rotation of the knob 44 at the upper end of the casing, which knob if desired may have appropriate scale markings (not shown), and the volume is controlled by turning the upper button 49.

. In performance, the arrangement of the loud speakerdiaphragm in a horizontal plane facing downward and the distribution of ports I I thereabout' and especially at the slits II in the top of thebase, makes for a better distribution of sound laterally of'the receiver in all directions than does theconventional small receiver in which the loud speaker faces forwardly for emission through the front panel. Moreover, by the arrangement set forth, the table, o rother support upon which the unit rests, may contribute markedly to the quality of output, depending on its sound reflecting or sound'absorbing characteristics, to act for any of the wide variety of sound-board effects.

It will be obvious that the casing may be made in any of numerous shapes. One desirable shape illustratively shown simulates a bottle, the tuning control knob 44 simulating the decorative trim ofth'e bottle neck and the volume control button 49-at the top simulating-therim of the stopper.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
